I was driving this weekend and my car began to act funny. The car actually stalled out twice.....and the check engine light came on and it stayed on after I restarted her again. I am not sire what code it threw but I am going to get my friend to scan it. She was hesitating and then a pop from under the car....WTF....I put dry gas into her and she ran fine.....I am beginning to think that my injectors are plugs or my opti is on the way out...or my fuel pump is going.....she hesitated once in a while....but the car just dieing...that never happened before....she died twice....took a few times to turn over and start. and she seemed ok......when I drive on highway, rpms are 1500...is that too low? I drove home with rpm's 2000+ and she ran strong...I am not sure what is goin on here....any insight would be great.

 

Check the code and go from there
